COMBINED WASHER-PLATE AND NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 473,086, dated April 19, 1892.

Application filed July 28, 1890. Serial No 360,184. 7 (No model.)

To 00% whom it may concern.-

Be it known that I, JOSIAH SCOTT, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in a Combined l/Vasher-Plate and Nut- Lock; and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,which form part of this specification.

This invention relates to a combined washer-plate and nut-lock.

The object of the invention is to produce a device of the above description which, when placed in position, will render the employment of the ordinary washer unnecessary, which will securely lock one or a series of nuts in place against all possibility of loosening or working off from the vibration incident to the passage of a train over the rails or the jar of machinery employing the same, which may be readily manipulated for the purpose of removing the nuts, and which shall be simple of construction, of high efficiency and durability in use, and cheapness of production.

With these objects in view the invention consists, broadly, in a washer-plate provided with a plurality of openings arranged at such distances apart as to engage with the bolts of a rail and arms formed integral with said plate and carrying shoulders adapted to rest between the said nuts.

The invention further consists in the va rious novel details of constructionof a combined washer-plate and nut-lock, as will be hereinafter fully described in the specification, illustrated in the drawings, and more particularly pointed out in the claims.

In the accompanyingdrawings, forming part of this specification, and in which like numerals of reference indicate corresponding parts, I have illustrated one form of device embodying the' essential features of my invention, although the same may be carried into effect in other ways without in the least departing from the spirit thereof.

In the drawings, Figure 1 is a side elevation of a section of rail, showing my improved device in place thereon. Fig. 2 is a perspective View showing the nuts, fish-plate, and com bined Washer-plate and nut-lock in place thereon, one of the arms of the latter being turned out to show the manner of releasing the nuts; and Fig. 3 is an elevationof the washer-plate.

Referring to the drawings, 1 and 2 designate two sections of rail, and 3 the fish-plate. As these are of the ordinary construction, a further description of them is not deemed necessary.

The combined washer-plate and nut-lock 4, which forms the subject-matter of this specification, is constructed, preferably, of a flexible metal and is provided with a series of openings 5, adapted to engage with the bolts 6, holding the sections of rail together. At a point near the center of this plate and extending to the end thereof, or approximately so, are two irregular slits 7 and 8, which form arms 9 and 10. The slits at their startingpoint are preferably at an angle to the edge of the plates for ashort distance, from which point they extend nearly parallel thereto and then dip downward and upward, so as to form shoulders 11 and 12 and fingers 13. The object of having the base 14 of the arms wider than the remaining portion thereof, excepting the shoulders, is to give rigidity thereto, so that when once turned to the desired position they will remain thus adjusted.

Having thus fully described my invention, I will explain the manner of its operation. The rails and fish-plate being in position, the bolts 6 are inserted through the same and the plate 4 placed over the ends thereof, both of the arms 9 and 10 being turned out as one of the arms is shown in Fig. 2. The nuts 15 are then turned to their seat and the arms turned down, so as to lie nearly flush with the fishplate, as shown inFig. 2,the shoulders 11 and 12 resting between the heads of said nuts, thus locking them securely in place, the fingers 13 also assisting in this feature. \Vhen it is desired to remove thenuts for any purpose, the arms are turned out, and after the adjustment has been completed they are locked in position in the manner described.

I would have it understood that I do not limit my invention to be used upon railwayrail joints alone, but may employ it for a number of purposes, as for binding bridge-timbers or parts of machinery together.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An improved nut-lock comprising a washer-plate having bolt-apertures produced therein and a slit and recess formed in the plate between the said apertures and a tongue integral with the Washer-plate, arranged to one side of the bolt-apertures, said tongue having a projection produced thereon which is adapted to lit the recess between the apertures and engage the opposing sides of the adjacent nuts, and thereby lock the nuts at their sides while the other portions of the tongue Will lock upon the top of the nuts.

2. An improved nut-lock comprising a Washer-plate provided with bolt-apertures and a JOSIAH SCOTT.
